{"version":"1.0","type":"rich","title":"Fork of Multiple Line Chart","description":"This visualization displays military spending trends from 2001 to 2020 across multiple countries, with each country’s annual spending plotted as a line over time, and the aggregated data using all points rather than separating by nation. It employs D3 v5’s `scaleLinear` for both axes, `line` with `curveBasis` to smooth the path, and `nest` to group the dataset by country, though the chart ultimately draws a single combined line. The SVG rendering includes custom axes with gridlines, a title, and axis labels, sourced from a CSV file containing country, year, and spending values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ec8c38a6b87945d58ac7919d0ba3aeb7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
